This software is intended for interactive or offline exploratory data
analysis.
What are feature vectors and why would one want to use them?
A feature vector in this context is an ordered collection of
attributes from the main list. This can be used to select
a subspace where a natural metric exists, i.e., the similarity of
objects can be compared in a meaningful way. The feature vectors
can be passed internally to pattern recognition algorithms or saved
for external analysis. The order of the list is used in a feature
vector (parallel coordinate) plot, that means it can be manipulated
to sort the coordinates in some useful way.
